AIIMS 2019 Zoology Somaclonal Variation Assertion Reason Question

Type: Assertion Reason-conceptual-Medium-Class 12

Assertion: Somaclonal variations produce slight differences in plant Reason: In bacteria, transcription and translation occurs in cytoplasm

A

If both assertion and reason are true and reason is the correct explanation of assertion.

B

If both assertion and reason are true but reason is not the correct explanation of assertion.

C

If assertion is true but reason is false

D

If both assertion and reason are false.

Correct Answer

Option C

Detailed Explanation

Option C is correct because the assertion that somaclonal variations produce slight differences in plants is true; these variations arise from genetic changes during tissue culture. However, the reason provided is false; in bacteria, transcription (the synthesis of RNA from DNA) and translation (the synthesis of proteins from RNA) occur simultaneously in the cytoplasm, not as a reason for somaclonal variation. Option A is incorrect because the reason does not explain the assertion, while option B is incorrect as it suggests both statements are true but fails to connect them. Option D is incorrect because the assertion is indeed true.
